Description of the object if any Methods
add_conversion
(typename, methodfull, methodraw)Adds methods to the Kernel class for new conversions as_ls
()as_np
()Converts this kernel to a Numpy-based representation as_raw_ls
()as_raw_np
()Directly return this kernel as a numpy array as_raw_sg
()Converts directly to a Shogun kernel as_sg
()Converts this kernel to a Shogun-based representation cleanup
()Wipe out internal representation compute
(*args, **kwargs)Generic computation of any kernel computed
(*args, **kwargs)Compute kernel and return self reset
()Base class for LIBSVM Kernels has no parameters

compute
(*args, **kwargs)¶ Generic computation of any kernel
Assumptions:
- ds1, ds2 are either datasets or arrays,
- presumably 2D (not checked neither enforced here
- _compute takes ndarrays. If your kernel needs datasets, override compute
